While performing in Moscow last week, Madonnaapplauded the courage of the all-girl punk trio, who at the time were on trial for staging a protest show at a Russian Orthodox cathedral in March. The Material Girl also appealed for their freedom.

But just as Pussy Riot's fitting new song, "Putin Lights Up the Fires," was dropping today, Nadezhda Tolokonnikova, Yekaterina Samutsevich and Maria Alyokhina were being found guilty of hooliganism.

"FYI. We will never being playing a show in Russia as long as they imprison innocent musicians for speaking their minds peacefully," Black Keys drummer Patrick Carneytweeted today upon hearing that the band had been convicted.

"These girls got sentenced to 2 years in prison for this. I assume we are in agreement that it's not ok. #pussyriot," wroteAdrien Grenier. "Two years in a Russian jail? Geez. That'll give em some song writing material," chimed in former House star Jesse Spencer.

"Thanks for the support on my Newsnight appearance. Keep the women of #PussyRiot in your hearts & (punk) prayers," tweeted the Scissor Sisters' Ana Matronic after appearing on BBC Newsnight to talk about the verdicts.

"There are not enough expletives to describe the injustice done to #PussyRiot today.My support is with them.Let's figure out what we can do," wrote singer-songwriter Annie Erin Clark, aka St Vincent.

"Solidarity shout-out to #PussyRiot! I signed a petition in support! Then I found out it was a band," he tweeted, along with, "I see #MittRomney and #PaulRyan have taken to calling themselves America's Comeback Team. Cuz #PussyRiot was taken."

"I and many others like me who believe in free speech will do everything in our power to support you and the idea of artistic freedom," wrote the Beatles legend.

Björk wrote on her website (also before the verdicts came down): "as a musician and a mother i would like to express i fiercely dont agree with them being put to jail because of their peaceful protest performance. they are currently standing trial and facing seven years in prison for this.

"in my opinion the russian authorities should let them go home to their families and children."
